"Bang… Bang…"
"Come on! Not enough! Still far from enough!"
Time passed little by little.
Every ten minutes, Ren had to exit the Netherworld Space.
But the blood-covered and heavily injured him would immediately activate the ocular technique Ōnamuchi again—
Instantly reentering that parallel world and continuing the battle with unyielding determination.
"Ha… ha…"
Who knew how long it had been.
Suddenly—
Ren appeared inside the room.
His entire body drenched in blood.
He collapsed to the floor, gasping for breath.
"Although I pushed myself too far… the effect is obvious…"
His voice sounded weak.
Yet there was no frustration or regret.
On the contrary—
In those eyes, where even the three-tomoe Sharingan was barely being maintained,
There shone an indescribable excitement.
Filled with obsession and madness.
"I can feel it… I'm constantly improving!"
He could see the path toward becoming stronger at an incredible speed.
A path where ninjutsu, taijutsu, and genjutsu developed together.
Where he could fight himself—
Force himself into desperate situations—
Break through his limits again and again—
And achieve complete transformation.
And when the wood clones dispersed,
They returned with valuable memories and combat experience.
The results were remarkable.
This method was cruel.
Extremely cruel.
If he made even the slightest mistake—
He might kill himself.
But it worked.
"If there truly are 'gods' in this world…"
Ren clenched his fist tightly.
His gaze burned with unprecedented madness.
"Then why can't that god be me?"
Anyone else would have abandoned such a crazy training plan.
But Ren wouldn't retreat.
His ambition—
His unwillingness to live an ordinary life—
Would never allow it.
Using the last of his chakra,
He set his broken bones back into place.
Combined with his astonishing regeneration ability,
He barely treated his injuries.
But with his chakra completely exhausted
And his injuries still severe,
The exhausted Ren could no longer hold on.
He fell unconscious.
Evening.
Tsunade, slightly drunk after having a few drinks,
Returned to the inn with Shizune.
The moment they saw Ren lying there—
Covered in sweat, bruised and swollen, and drenched in blood—
Their expressions changed drastically.
They froze.
"Ren—!"
Shizune panicked instantly.
Without hesitation, she dropped Tonton.
She rushed forward in alarm.
"Ren… blood…"
Tsunade, however,
Collapsed onto the ground.
Her body trembled uncontrollably.
Unable to move.
Her eyes were filled with fear, worry—
And an indescribable anger—
As she stared at the blood-covered Ren.
"What… happened here?"
"Ren, what's wrong? Wake up!"
Holding the unconscious Ren,
Shizune was filled with worry.
Tears streamed down her face.
"This is all my fault! I shouldn't have left you alone!"
As a medical ninja,
She quickly examined his body.
After confirming that his life wasn't in immediate danger,
She finally let out a small breath of relief.
But when she discovered the condition of his internal organs—
Her expression changed drastically.
They had suffered varying degrees of damage.
If not for his incredible regenerative ability,
He might already have been on the brink of death.
"H-how is he, Shizune?"
Tsunade gritted her teeth.
She remained slumped on the ground.
Her body trembling uncontrollably.
Looking at Ren's young face—
Still bruised and swollen—
Even his abnormal regeneration hadn't fully healed it yet.
One could imagine how brutally he had been injured.
At this moment,
Seeing her disciple lying there covered in blood—
And realizing she, his teacher, could do nothing—
Tsunade felt an overwhelming hatred toward her own weakness.
Just because of her hemophobia—
She couldn't even stand up.
Damn it!!!
"Lady Tsunade, his internal organs are injured, and he has multiple fractures across his body… It looks like he went through an extremely intense battle."
Shizune carefully examined every injury.
At this moment, she didn't have time to worry about Tsunade's hemophobia.
Her hands formed seals rapidly.
A soft green light appeared in her palms.
She pressed them against Ren's chest, accelerating the healing of his damaged organs.
Without lifting her head, she replied through gritted teeth.
"However… his body has an astonishing regenerative ability. It's slowly recovering…"
Ren's injuries made her gasp.
What kind of battle could injure someone like him so badly?
His recovery ability was comparable to that of a Nine-Tails Jinchūriki—
Maybe even stronger.
And yet he had been beaten into this state.
And somehow—
She had a strange feeling.
Many of the injuries looked like they had been caused by Monster Strength Fist.
Could it be…
"No… impossible."
Shizune's expression changed.
She quickly rejected the thought.
She had been with Lady Tsunade the entire time.
It couldn't have been her.
And Tsunade would never hurt Ren.
There was absolutely no reason for it.
"Who did this…?"
Seeing her beloved disciple lying there unconscious,
Tsunade trembled violently due to her hemophobia.
Her heart suffered wave after wave of shock.
Pain appeared across her face.
The image of her younger brother Nawaki—
His bloodied and lifeless body lying in her arms—
Once again surfaced in her mind.
"AHHH… DAMN IT, GET UP!!!"
Her fists clenched tightly.
Her pupils trembled.
Then gradually—
Her expression hardened.
Her killing intent surged.
Ignoring her hemophobia,
Tsunade suddenly stood up.
"Damn it… who the hell hurt this child like this?!"
Her face turned ice-cold.
Terrifying killing intent radiated from her.
"I won't forgive them!"
Although they hadn't spent much time together,
Perhaps because the blood of the Senju Clan flowed in both of them—
Tsunade had already begun to treat Ren like a younger brother.
"Shizune, let me handle it!"
"Lady Tsunade—you…"
Shizune was shocked.
But at the same time, joy flashed in her eyes.
She instinctively stepped aside.
"Don't say anything else."
Tsunade's face remained filled with killing intent.
She didn't even feel excited about overcoming her hemophobia.
She carefully examined Ren's injuries.
But soon—
Her expression suddenly changed.
"Monster Strength Fist?! How… how is that possible?"
Although some people were naturally strong,
There was still a huge difference between raw physical strength
And the explosive power released by Monster Strength Fist infused with chakra.
As a highly experienced medical master—
And someone extremely skilled in Monster Strength Fist—
Tsunade could tell almost immediately.
Most of these injuries—
Were very likely caused by Monster Strength Fist.
"Lady Tsunade… I also suspected that earlier, but I wasn't sure…"
Shizune said quietly from the side.
"Who exactly injured him like this?"
Tsunade's expression kept changing.
Filled with shock and suspicion.
But as she continued healing Ren,
She also let out a small breath of relief.
"Fortunately… although his internal organs are damaged, his recovery ability is far beyond normal. It's not life-threatening."
"And before losing consciousness…"
"He should have treated himself."
